I. 0. SILVER
by Brad Wilhelmsen
I. O. SILVER is a hi-res strategy/arcade game for the Apple II series of
computers. Dr. I. 0. Silver is a semi-world famous hi-res scientist and
renowned hardware nut. The Professor is forever attempting to build the
new fifth generation "Super Computer" from the array of integrated circuits
(computer chips) on the Apple screen. Your job is to help him out.
The only hardware required to play I. 0. Silver is any version of Apple II
and a disk drive. Well, o. k., you do need a monitor — a color monitor will
add color to the game, but a non-color screen will work just as well. If you
have a monochrome monitor (green screen, black-and-white, etc.), you can
discern the different colors by the patterns on the playing pieces. Whenever
we refer to "color" in these instructions, we also mean "pattern".
You can play the game using only the keyboard (our favorite way), but a
joystick is an optional accessory (and besides, after a few years, if you tire
of the game, the I. 0. Silver disk and a joystick can be used for a rousing
game of floppy ring toss).
BACK IT UP
In keeping with Beagle Bros tradition, the I. 0. Silver disk comes from the
factory unlocked and unprotected. "Unlocked" means that if you're into
machine language — or would like to be— you can inspect or change the
game to see what makes it work. "Unprotected" means you can copy the
disk with the standard Apple copy program that came with your Apple.
That way if your original disk fails (or falls into the fish tank), you've got a
replacement. Make a backup of the disk now; we'll wait here.
US CRAZY? NO WAY, JOSE!
Selling a copyable game disk is considered by some in our industry to be
what's known as— in business terms — a "dumb move". We heartily
disagree, and believe that making software more friendly makes it a more
valuable product to you, our valued customer. Please support our efforts by
not giving copies away to your friends. Every illegal copy you see or use is
a vote FOR copy protection and AGAINST friendly software. You support
us, and we'll support you.
SOURCE CODE AVAILABLE
Some of you advanced programmers might be interested in obtaining the
source code for I. 0. Silver. If so, check the Appendix (page 20).
The Object of the Game
GET RICH BY PUSHING CHIPS!
The object of I. 0. Silver is to move the Professor around the screen and
push together all of the chips of the same color, thus combining them and
creating other parts which ultimately create a Super Computer. For each
Super Computer built, you get a hi-res medal and tons of imaginary cash.
Short of that lofty goal, the object is to survive and earn as much money
as possible by combining as many chips and other computer parts as you
can. High scores are saved on disk at the end of each game. Besides
getting the all-time highest score (and becoming famous), there is no way
to actually "win" the game.
You will work within a one simulated-year deadline and constantly be
harassed by a gang of computer "bugs" which will try and rob you of your
most valuable asset— time. You can, however, earn even more money by
trapping these pesty critters.
TWO WAYS TO PLAY
You may play two different versions of I. 0. Silver— the high-pressure
"ARCADE WORKSHOP" or the take-your-time "STRATEGY LAB". See
page 6 for details.
Summary of Game Controls
I, J, K or M: Moves or turns the Professor, OR pushes (if not blocked) the
adjacent chip that the Professor is facing— up, left, right or down.
CONTROL-C: Lets you change from I/J/K/M to another set of keys.
CONTROL-A: Switches to joystick (instead of keyboard) control during the
game. You may adjust your joystick when the switch is made.
JOYSTICK STICK: Moves or turns the Professor in the direction selected.
JOYSTICK BUTTON (either one): Pushes (if not blocked) the adjacent
chip that the Professor is facing.
CONTROL-C: Lets you adjust your joystick for proper centering.
CONTROL-B: Switches to keyboard (instead of joystick) control during the
game. You may optionally change from I/J/K/M to another set of
keys when the switch is made.
CONTROLS: Toggles the sound on and off during the game. (Remember,
if you have an Apple with a volume control, be sure the volume is not
all the way down if you want sound.)
ESC: Ends the current level (Note: The Arcade Workshop version requires
at least as many execution points as the level number to end a level —
RETURN: Lets you take a vacation and study the screen to plan your next
set of moves (Arcade Workshop only).
CONTROL-RESET (not recommended): Stops everything in its tracks and
forces you to re-boot a disk.
Summary of How to Play I. 0. Silver
(The small numbers like " 1S " are page references for more information.)
■ BOOT THE DISK by inserting it in your main drive and turning on
your Apple. You will see the Disk Menu with its I, and S options. 6
■ PRESS "I"— You will soon see the game's Title Screen.
■ PRESS ANY KEY when the drive stops— You will see the main menu. 6
■ PRESS "1" to play the Arcade Workshop version 6 of the game (or select
one or more of the other options). 6 You will see the chip values. 8
■ PRESS ANY KEY and you will see the Laboratory (playing screen. 9 )
PLAYING THE GAME—
Some Rules Before You Start: I. 0. Silver is played on advancing "levels" 13
numbered from 1 to 26. You have a one year time limit on each level,
indicated by the calendar 9 at the top of the screen. If time runs out, it costs
you one Professor. 13 You are given three Professors to start the game (you
only play with one at a time).
■ PRESS ANY KEY to release the bugs and begin playing the game. Move
the Professor 11 , dodging the bugs as much as possible. Push the chips 11 to
combine as many of the same color (and pattern) as you can. When all the
chips of one color are combined, they become a "circuit board", 12 which
may be combined to create other parts, 12 which ultimately, if you're good
enough, will combine down to become one object— the Super Computer,
earning you a well-deserved medal and the biggest prize money.
Each chip combination and new object created (like a circuit board)
earns you money. You may also trap bugs 15 between chips to earn more
money and, at least temporarily, get them off the screen.
Creating any new part (like a circuit board) gains you one or more
"execution points". 13 If the number of execution points equals or exceeds
the current level number, you may press ESC and go on to the next level, 13
where you will start over with a new batch of chips. OR you may continue
earning money by building on the current level.
If time runs out (on DEC.31), the level will end and you will get to
replay the same level (unless you have used all three of your Professors; 13
then the game is over).
Your earnings and the number of Professors remaining will be reported
between levels in an "annual report". 16 High scores and in-progress games
may be saved on disk. 18
Features of the Game
■ THE DISK MENU
This menu will appear when you turn on your Apple to boot the disk:
(I) PLAY I. 0. SILVER
(0) OTHER STUFF
(S) STOP FOR NOW
"Other Stuff' is self-explanatory; try it sometime. "Stop for Now" is rather
boring and not recommended. PRESS THE "I" KEY to play I. 0. Silver.
■ THE MAIN MENU
When you see the game's title screen and the disk drive stops,
PRESS ANY KEY and the following list of options will appear:
1. ARCADE WORKSHOP
2. STRATEGY LAB
3. SEE HIGH SCORES
4. SEE SAVED GAMES
5. SELECT JOYSTICK (or ADJUST JOYSTICK)
6. CHANGE KEYS (or SELECT KEYBOARD)
7. SOUND: ON (or SOUND: OFF)
8. TV: COLOR (or TV: MONOCHROME)
At this point you may simply PRESS "1" OR "2" to play the game, or
make adjustments by selecting one or more of the other options. Following
is an explanation of all the Main Menu options.
Options 1 and 2 —
Select one of these two options (press "1" or "2") to start playing a game.
You decide which of these two versions of I. 0. Silver is for you:
This version of I. 0. Silver has more action. It is also more pressure-
packed, since you are given a firm deadline and a room full of "bugs"
that are out to zap you and bring that deadline even closer.
This version of I. 0. Silver puts no time limit on you — you can take all
day to make a move — and bugs are prohibited. After trying the game
both ways, the Strategy Lab may be the only version you want to play.
Or you may want to use it to practice or to plan an attack that can be
used in the Arcade Workshop, (see page 18 for more details)
Option 3— SEE HIGH SCORES
This option lets you look at the highest Arcade Workshop scores (if any)
that have been saved on the disk that is currently in your main drive.
Option 4— SEE SAVED GAMES
This option lets you see a list of up to ten in-progress Arcade Workshop
games that were saved (by you) on disk. You can select one of these games
(thus removing it from the disk), if any exist, and continue playing it at
the point from which it was saved.
Option 5— SELECT (or ADJUST) JOYSTICK*
This option lets you control the game with a joystick (instead of the Apple
keyboard), or adjust it if it's already selected. (When the disk is first booted,
the keyboard is automatically the controlling device.)
Option 6— SELECT (or CHANGE) KEYBOARD*
This option lets you play with the keyboard (instead of a joystick). If the
keyboard is already selected, you may use this option to change the keys —
I, J, K and M — that control the game. (Beagle Bros is not responsible for
injuries suffered when using the I/J/K/M configuration.) The four arrow
keys (found on some Apples) are an obvious, but BAD alternate key choice,
we think, because of the way they are positioned on the keyboard. You
might like to try two-handed operation by choosing A & Z (up & down)
and the left & right arrows (left & right).
Option 7— SOUND: ON (or OFF)*
To toggle the sound on and off, press the "7" key. If you hear a tone, I. 0.
Silver will be played with a variety of beeps, buzzes and music. Don't
forget — if your Apple has a volume control, turn up the volume.
Option 8— TV: COLOR (or MONOCHROME)
If you select Monochrome, the game will simply be played with more
contrasting colors. Both versions work with both kinds of monitors.
Option 9— QUIT
This option will let you boot a disk.
* You may also control this feature while the game is running.
See SUMMARY OF GAME CONTROLS on page 4.
Chip and Bug Values
Before each level begins, you will be shown the values for combining chips
and trapping bugs. The screen will look something like this:
1 .0, SILUER.
si n sm
DEBUGGING BOHUS: $18,888 TO $25,888
TIRE BOHUS • $258 PER DAY
PRESS ANY KEY
At the top right is the upcoming level number. Under that are the six
different color chips and the values that will be obtained by combining two
chips of that color. The "De-Bugging Bonus" is the amount earned if you
can end a level with no bugs (page 15). The "Time Bonus" is the amount
you will earn for each day remaining on the calendar when you end a level.
The values under the four bugs at the bottom are the amounts earned for
trapping each one.
The values shown on this screen increase on each level. The values for
combining parts other than chips (like circuit boards) do not increase. See
page 14 for these values.
The Playing Screen
The I. 0. Silver playing screen consists of a one-line scoreboard at the top
and a laboratory full of chips below:
At the top of the screen there are four indicators of the progress of the
game at the current level:
CALENDAR (Arcade Workshop only): On the left is the calendar. It begins
at "JAN.01". When it reaches "DEC.31", the level ends. When you are
zapped by a bug, the date will increase by a number of days, depending on
which bug was the culprit (page 15).
VACATION INDICATOR (Arcade Workshop only): To the right of the
calendar are four small dots. These dots show how many vacations you
have remaining in the current level (see RETURN on page 4).
LEVEL NUMBER: To the right of the vacation indicator is the current
level number, a colon and the number of execution points earned so far
MONEY EARNED: At the far right is the amount of money earned so far
on the current level. It is not the total score for the whole game. That will
be printed as "Career Earnings" in each annual report (page 16).
THE PLAYING SCREEN (continued)
Below the scoreboard is the laboratory itself, a field of computer chips
ready to be pushed and assembled by the Professor. There are three main
things you must know about this imaginary workshop:
■ The Professor is not strong enough to get two chips moving at the same
time. Therefore, you cannot push a chip when there is another chip (of
a different color) blocking it.
■ Everything "wraps around" in every direction — the movement of the
bugs, the chips and the Professor. Think of the screen as a flattened-out
"sphere" if you want. This means that if you're near the bottom of the
screen, the fastest way to the top is down. The fastest way from far left
to far right is left. And so on.
■ Last but not least, YOU MUST BE CAREFUL when you push a chip to
make sure there is another one in its path to stop it. If there isn't, the
pushed chip will keep going, wrap around the screen and CRUSH YOUR
BODY, forcing an early retirement and ending the current level with one
Professor down the drain. Painful and embarrassing.
If the Professor (P) pushes the chip (C) upward,
it will wrap around and DESTROY him (D).
Moving the Professor and the Chips
Practice makes perfect. Or so they say. You will probably learn more by
messing around with the game than by reading this page. Read it anyway.
Pressing the I, J, K or M key will cause the Professor to walk up, left, right
or down, respectively. He will walk (or at least turn) in the direction
selected until he runs into a chip, or until you press another direction key.
You may press a key a little in advance of a move, and the Professor will
remember. Sorry, no stopping between chips.
Once the Professor has stopped at a chip, you may press the direction
key again to push that chip (if another chip isn't blocking it). Or press one
of the other keys (I, J, K or M) to walk (or at least turn) in another
If you are using an Apple like a lie or He (with a built-in repeat-key
function), DO NOT HOLD THE KEY DOWN when you move the
Professor. If you do, he will walk up to a chip AND push it. This is
something you will often not want to do. All moves in this game,
intentional or not, are irreversible.
If you don't like the I/J/K/M configuration, change it from the main
menu before the game starts, or by typing CONTROL-C during the game.
The joystick works much like the keyboard (see above). The stick moves
the Professor, and either button pushes a chip. Just a slight push of the
joystick will move (or at least turn) the Professor in the direction selected.
Once you see movement, let the stick spring back to its center position.
Pressing either one of the buttons on the joystick will push an adjacent
chip (if another chip isn't blocking it) in the direction the Professor is
If the Professor keeps going a direction you don't want him to, your
joystick may not be centered properly. Try adjusting it by pressing
CONTROI^C during the game. If this method fails, you'll have to use the
When a level starts, the object is to combine as many same-color chips as
possible, eventually making other "advanced parts". (Every part other than
a chip is referred to as an "advanced part".) Ultimately, when there is only
one shape left, you've got the Super Computer.
Each time you combine two same-color chips into one, you earn a
certain amount of money. When all of the chips of one color have been
combined, they become a new part — a CIRCUIT BOARD. Circuit boards
combine with other circuit boards and parts (but not with chips) to make
other advanced parts, which combine to eventually make a Super
You have the opportunity to build one Super Computer on every level.
Each time you do, you will receive a Medal. Your Medals will be
prominently displayed in the annual report and tallied on the high score

WE REPEAT (in case you've been asleep):
ONLY MATC HI NG-COLOR CHIPS MAY BE COMBINED.
ADVANCED PARTS COMBINE WITH ANYTHING EXCEPT A CHIP.
Levels and Execution Points
When you start the game, you will play on Level 1. If you complete Level
1, by earning enough "execution points", you will advance to Level 2 —
starting over with a different arrangement of chips — on up as high as you
can go (26 is the highest level, and probably impossible; let us know).
COMPLETING A LEVEL
To successfully complete Level number x, you must earn x execution
points. Execution points are earned by turning one or more types of parts
into another. For example, if you push the last two black chips together to
make a circuit board, you will earn 1 execution point, enough to complete
Level 1. If you build 2 circuit boards, you get 2 execution points, enough
to complete Level 2. Creating other types of parts is worth even more (page
14). All of these accomplishments also earn you big bucks, but money is
not directly a factor in completing a level.
When the number of execution points totals the current level number,
the two numbers after "Level" at the top of the screen will match, a special
sound will play, and you will (undoubtedly) feel a warm glow of
satisfaction. But the level does not automatically end at this point. You
have two options— hit the ESC key to quit the level and earn a bigger
Time Bonus, or keep playing to build more of the Super Computer.
Some Free Advice: Push two circuit boards together whenever possible.
Apart they are worth 2 execution points, but pushed together (making a
calculator), they are worth 4 points, enough to complete Level 4. This is
much easier than trying to make 4 circuit boards.
FAILING TO COMPLETE A LEVEL
■ If the calendar hits "DEC. 31" before you have enough execution points,
you will lose one of your 3 Professors and have to replay that level. IF
you have any Professors left, that is. If you don't, the game ends.
■ If there are no possible moves left (if there are no chips in line with each
other and no chips can be pushed) the level ends.
■ The worst way to end a level is by pushing a chip which is not in line
with any other. The chip will wrap around the screen AND CRUSH
YOU, forcing you to play that level again, regardless of the number of
execution points earned so far in that level. Any Time Bonus or De-
Bugging Bonus you earned will be lost. You will also lose one Professor.
You will become depressed.

The primary goal of I. 0. Silver is to earn money. Earning execution points
is important too, since they let you advance to the next level, thus buying
you more time and increasing the values for combining chips and trapping
bugs (see next page).

These are not your garden variety of crawly bugs, but the kind that prowl
the computer world. When you are touched by a bug, you do not lose the
game and the level doesn't end. What you do lose is time (sound familiar,
programmers?). And your one-year deadline gets closer.
The best defense against the bugs is to AVOID THEM. Your only anti-
bug weapons are the chips and other parts. Smashing a bug between two
chips of different colors will trap it temporarily. You will earn from $1,000
to $4,000 on Level 1 for doing this kind of "error trapping". (The point
values for the bugs, like the chips, increase each level.) However, if you
later move either of the chips that a bug is trapped between, it will escape.
Another more effective (and more profitable) way to eliminate a bug is to
trap it between two chips of the same color. You will earn double value for
combining the chips. Smashing two bugs at the same time triples the
dollar value, smashing three quadruples it, and four bugs quintuples the
money earned. Plus you also get a big De-Bugging Bonus if you can end a
level with all of the bugs gone. But watch out — if you get zapped by a
bug, all trapped bugs will be released.

The Annual Report
At the end of each level, you will be shown an Annual Report, looking
something like this:

HIT ESC TO
The Annual Report is a summary of how well you did on each level. Here
is a rundown of each of the Annual Report categories:
NUMBER OF PROFESSORS (pictured)
The number of Professors remaining are pictured at the top right of the
screen. At the start of the game you have 3. You lose 1 every time you do
not complete a level. You get another Professor (up to 8 maximum) every
time you complete an even-numbered level, beginning with Level 2.
NUMBER OF MEDALS (pictured)
Every time you build a Super Computer, you get a Medal. Your Medals will
be pictured below the Professors.
The most recent level completed.
This number indicates how many execution points were earned on the
most-recent level. If the execution points are greater than or equal to the
level number, then you have completed the level. The only exception is if
you smashed yourself with a chip. Then you must play the level again.
How many times you pushed a chip on the previous level.
This number shows how many chips remained when the level ended. If
you pushed all of the chips together into circuit boards, the number would
How many bugs you trapped on the previous level.
How many times the bugs got you.
How many vacations you used.
This amount is earned by quitting a level with days remaining on the
calendar. The Time Bonus begins at $250 a day on Level 1, and goes up
$25 per day for each level.
This amount is earned by ending a level with all of the bugs trapped.
$10,000 is the reward. You get a $25,000 bonus when ALL of the bugs
have been smashed between chips of the same color. If any bugs are loose,
the bonus is zero.
This amount is all of the money earned on the previous level. When you
begin the next level, this value goes back to zero.
This amount is the sum of all earnings so far in the game. At the end of
the first year, Total Income and Career Earnings will be the same amounts.
After that, Career Earnings will (hopefully) be larger.
Saving Games In-Progress
When you are in the Arcade Workshop, you can save the game in progress
at the end of any level. You might want to do this just to take a break. Or
you might want to go to the Strategy Lab (via the main menu) to try out
the next level.
IMPORTANT: DON'T SWITCH DISKS. YOU MUST SAVE
IN-PROGRESS GAMES ON THE I. 0. SILVER GAME DISK.
Press the ESC key when you see "Hit ESC to save game" (at the end of
a level only). Enter your name (or any word, up to eight characters), press
RETURN and your game will be saved to the disk. (Be sure you have a
good, DOS 3.3, non-full, non-write-protected disk in the drive, with the
drive door closed. If you don't, you'll get a "Disk Error" message.)
When you want to continue a saved game, choose item 4, "See Saved
Games", from the main menu. Enter the letter of the game you want to
play, and you will automatically enter the Arcade Workshop. That game
will be deleted from the Saved Game list. Of course, you can save it again
at the end of the next level.
A total of ten games can be saved. If you try to save an eleventh game,
you will first be asked to select a game to be dropped from the list. If you
don't want to lose any of the previously saved games, press ESC to keep on
playing the current game.
Strategy Lab Differences
As we mentioned before, you may choose to play I. 0. Silver's "Strategy
Lab" version by selecting it from the main menu (page 6). The Strategy
Lab is less hectic than the Arcade Workshop. There is no calendar, no
deadline and no bugs. You can relax and play at your own speed. Each
level in Strategy Lab is identical to the same level number in the Arcade
Workshop. You can plan your attack here, and then tackle the Arcade
Workshop. Or you may want to play the Strategy Lab exclusively. A lot of
Before going in the Strategy Lab, type the level you want to play. You
can choose any level from 1 to 26. You may leave the level at any time by
pressing ESC (no execution points are needed here).
A level will end when you press ESC, or when there are no possible
moves left, or when you smash yourself with a chip.
Strategy Lab games cannot be saved.
Tips on Playing I. 0. Silver
Here are some general strategies that will help you enjoy the game, get
higher scores, and impress your friends:
■ DON'T PUSH CHIPS RANDOMLY. In fact, don't push a chip AT ALL
unless it fits in with a plan of aligning and combining with other chips.
You can't take moves back, and it's easy to get carried away trying to
smash bugs. But you cannot complete a level just by smashing bugs; you
must build circuit boards and earn execution points.
■ NEVER CREATE A BLOCK OF FOUR CHIPS. The chips will become
locked together and you won't be able to push them, making it very
difficult or impossible to complete a level.
■ CONCENTRATE ON CHIPS OF ONE COLOR. Decide to combine all
of, let's say, the white chips (these have the highest point value) to make a
circuit board. Then, take a vacation and study the screen for a new plan.
■ WAIT FOR THE BUGS TO COME TO YOU. The best way to smash
bugs is to find a push that helps you strategically, and wait for a bug to
enter the line of fire.
■ TAKE ADVANTAGE OF WRAP-AROUND. If a chip looks blocked, don't
give up. Maybe you can move it to an advantageous position by pushing it
in the opposite direction.
Remember that two chips at opposite edges of the screen are actually
touching each other. Also, don't waste time running across the screen to
get to the other side.
Hanging around the center of the screen will keep you from being
attacked from the "blind side" by bugs.
■ USE NON-VACATION PAUSES FOR LUNCH BREAKS. Rather than
use up your valuable vacations, press CONTROL-C. This will put you in
the keyboard or joystick adjust mode and temporarily stop the game, not
costing any vacation time. The only problem is, you can't see the Lab.
■ DON'T FORGET THE ESC KEY. This will quit the level when you have
enough execution points. If the position looks bad, take the Time Bonus
for any remaining days on the calendar.
■ WAIT TO COMBINE PARTS. The fewer the number of parts left on the
screen, the more difficult the game becomes. With this fact in mind, don't
push parts together unless necessary. Just get them lined up with each
other. When you are ready, try to make a clean sweep. Author's note: This
is easier said than done. Good luck!
TECHNICAL STUFF ABOUT THE DISK
The I. 0. Silver disk is a normal DOS 3.3 disk. You can boot it, catalog it
and look at its programs to your prying heart's content. After you have
played I. 0. Silver, however, DOS 3.3 will necessarily be rendered
inoperable (Brad had to murder DOS to make the game fit in 48K). The
only thing resembling a DOS command that will work is "PR # 6", which
will reboot the disk.
If you want to Run any of the other programs on the disk, do a fresh
boot on the I. 0. Silver disk or any normal DOS 3.3 disk. To look at the
I. 0. Silver game code, you'll need to move DOS to the Language Card.
(Beagle Bros' ProntoDOS moves DOS 3.3.)
Sorry, we can't answer technical questions about how I. 0. Silver was
written, because we don't know. The author lives in Japan, and we'd give
you his phone number, but (we've noticed) it's always 3 a.m. over there-
I. 0. SILVER SOURCE CODE AVAILABLE
If you are an advanced machine language programmer (or would like to
become one some day) and you would like a copy of the source code for
I. 0. Silver, mail $30.00 to Beagle Bros (address on back cover) along with
the "Proof of Purchase" corner clipped from the back cover of this manual
I. 0. Silver was written with Merlin (Roger Wagner Publishing) and
should be compatible with most other assemblers. The code occupies a
whopping three disks (both sides) and is fully commented. There is no
printed matter included, but you can dump the code on your printer.
Sorry, technical questions about the program or the source code can NOT
be answered — you're on your own.
